TYPE-CASTING MACHEN E.

SPECIFICATION forming part of Letters Patent No. 678,831, dated July 16,1901.. Application tiled February 17, 1900. Serial No. 5,587. (Nomodel.)

.To all whom it may concern:

Be it known that I, GEORGE H. ZIEGLER, a citizen of the United States,residing in Philadelphia, Pennsylvania, have inven ted certainImprovements in Type-Casting Machines, of

which the following is a specification.

My invention relates to certain improvements in type-casting machines inwhich the type is cast, dressed, and finished.

1o The obj ect of my invention is to perfect the details of the machineillustrated and described in the Patent No. 376,765, of January 24,1888, and in the application for patent, Serial No. 576,036, led January18, 1896. This object I attain in the following manner, reference beinghad to the accompanying drawings, in which- Figure 1 is a front View ofmy improved type-casting machine. Fig. 2 is a transverse zo sectionalview on the line 2 2, Fig. 1. Fig. 3 is a sectional plan view of themold portion of the machine. Fig. 4 is a section on the line 4 4, Fig.3. Fig. 5 is a section on the line 5 5, Fig. 4. Fig. 6 is an enlargedsectional view showing the matrix-holder. Fig.

7 is a plan View of the matrix-holder illustrated in Fig. 6. Figs. 8, 9,and 10 are detail views of the matrix-holder. Fig. 11 is a detail viewof the rear carrier-plunger.

3o Fig. 12 is an end View of Fig. 11. Fig. 13 is a view showing themeans for adjusting the body-piece. Figs. 14 and 15 are perspectiveviews of details of the mechanism shown in Fig. 4.

3 5 A is the base of the machine, having bearings for the shaft B, whichcan be either driven by hand or power. On the base is a frame A',carrying the moving parts of the machine.

4o O is a melting-pot for the type-metal, pivoted so as to swing clearof the operating parts of the machine when desired.

The mold `for the type is formed by two side plates D D, Fig. 4, thebody-piece E, and

the plunger F. The body-piece is adapted to the space between the platesand acts as the bottom of the mold, and the sliding plunger F acts asthe top of the mold and carries the type from the mold to thetype-channel. In-

5o serted in the bottom of the plunger is a block f, held by a screw f.This block rests din rectly over the mold during the casting of thetype, as clearly shown in Fig. 4. The nipple c of the melting-pot iitsagainst a perforated plate c', Fig. 5, so that there is a tight joint 55 between the mold and the melting-pot.

G is the matrix-carrier. This matrix-carrier is clearly shown in Figs. 6to 10, inclusive, and slides upon the projection of the frame A and hasa pocket g, Fig. 2, at its 6o forward end, in which rests a dependingportion g of the table G', on which the matrix i is clamped. Extendingfrom the depending portion g is a rod Q7, around which is a spring g2,tending to force the plate upward.

g3 is a yoke secured to the matrix-carrier G. This yoke has doubleset-screws g4, which carry the upper clamp-plate g5.

On each side of the depending portion g of the table G are guide-barsgs, which enter 7o holes in the matrix-carrier, so as to hold the tableG in position. The upper surface of the table G is grooved at 7i, andadapted to this groove is a plate H, confined by a screw h to the tableG. The screw passes through the slot in the plate H, and the plate hastwo lugs h2, as shown in Fig. 9.

H is a U-shaped piece having two projections hs, resting back of the lugh2 of the plate H and provided with adjusting-screws h4, 8o which bearagainst the rear of the lugs. Projecting from the piece H are two pinsi', which enter holes in the bottom of the matrix c', so that the matrixwhen in position is held from turning by these pins.

The :matrix-carrier G is provided with the usual sp1-ue I, which restsagainst the rear of the matrix and is adapted to a socket in theprojection of the matrix-carrier, so that the sprue can adapt itself todifferent matrices. go

The matrix-carrier G is actuated by a lever G2, pivoted to the frame ofthe machine and acted upon by a cam b on the shaft B. The cam in thepresent instance rests against a roller on the lever, and a springGtends to keep the roller against the cam, as clearly shown in Fig. 2.

The above-described matrix-carrier and its connected mechanism is fullydescribed and claimed in an application for United States Ico patentfiled by me June 7, 1901, Serial No. 63,588.

B, Fig. 1. lThe lever E2 is adjustable; but I do not claim theconstruction of this lever.

The slide is so set that its extreme upward movement will bring it flushwith the top of the plates D D; but its downward movement Io isregulated by a wedge J, Fig. 13, the tapered end j being adapted to anopening e4 in the slide. The wedge is moved in and out by a handled nutJ, adapted to the threadedy endj of the wedge J, the nut being confinedI5 to the bracketj2, projecting from the base of the machine, as clearlyshown in Fig. 1.

In order to set the machine to cast a given type, it is necessary toaccurately adjust the wedge J so that the space between the bodypieceand the top of the mold when the bodypiece is down will be the exactwidth of the type to be cast. To accomplish this quickly, I mount on thefront of the machine a bracket e2, in which slides a plunger e', and inthe z5 bracket above the plunger is a headed setscrew e3.

Projecting from the body-piece slide E is an arm E3, which extends underthe plunger e', as shown in Figs. 2 and 13. When it is 3o wished to setthe mold to cast a type of a given thickness, a type or a blank of thethickness required is placed between the plunger e and set-screw e2, andthe wedge J is adjusted until the type or blank is gripped between thepluugerand set-screw. Then the type or blank is removed and the machineis ready to cast type of the thickness required.

Vhen the type is cast, the sliding plunger F moves back to allow thetype to `be pro- 1,0 jected up in front of it. As the plunger movesforward it pushes the type forward on the plate D to the channel s.

At the end of the plunger F is a clamp K, and secured to the plunger isa plate n, Fig.

15, which extends under the clamp, and between the plate and the clampis a spring 7o, which tends to elevate the clamp. Secured to an armprojecting from the clamp is a plate 7c', preferably the size of thetype or smaller.

5o The form of this plate is clearly shown in the perspective View, Fig.14.

"K is a lever pivoted at 702 to the sliding plunger F. This lever hasa'roller 7c3, which passes under an arm K2, beveled on the under side,and the other arm of this lever K presses upon a pin 7c4 on the clamp K.

765 is a set-screw for regulating the movement of the lever K.

When the sliding plunger moves back, so

6o as to allow the type to be projected from the mold, the roller 7c3passes under the arm K2, relieving the clamp K from pressure of thespring k6, and its spring 7c will elevate it to allow the type to beraised clear of the mold.

As soon as the plunger moves past the mold the lever K moves from underthe arm K2, and the spring 7c, which acts upon the lever 707, forces theclamp K down upon the type to hold the type rigidly until it passes to aposition directly over the channels. When the plunger is in this lastposition, the clamp K is forced down by a rod L, actuated by a cam 7 onthe shaft B. The clamp thus pushes the type into the channel s, clear ofthe sliding carrier, and moving forward all the type in the channel.

The type as it is moved forward is clamped between the sliding plunger Fand the sliding plunger F', Fig. 11, this latter plunger being backed bya spring m on a rod m', attached to said plunger on a rod m', so that asthe plunger F moves forward it compresses thev spring through the mediumof the type and pushes the plunger F within its box M. Thus the type isrigidly held while being carried from the mold to the channel. The rod mis secured to the rearend of the plunger F and has a nut m2 and ajam-nut at its outer end. On turning the nut m2 the distance between theplungers F F' at the mold can be regulated, as when the plunger F isforced forward by its spring m, as in Fig. 1, the nut m2 strikes the endof the boXvlVI, and thus the movement of the plunger F is limited, sothat on adjusting the nut the space between the plungers will beincreased or decreased. The plunger F' has a notch f", with whichengages a latch f3, having a head f4. head and the casing for the latchis a comparatively light spring f2, which tends to raise the latch.

Vhen it is desired to withdraw the plunger F', all that is necessary isto draw it back the full distance and press upon the head f4 of thelatch, which will force the latch into the notch f2 of the plunger. Thepressure of the spring fm, will cause the plunger to bear Between thisIOO with suflcient force against the latch to hold it in engagement; butwhen it is desired to release the plunger all that is necessary is topull upon it slightly and then release it, causing the latch to releaseitself from engagement with the plunger and allowing the plunger to moveforward.

f6 is an adjustable stop to limit the forward movement of the plunger F.

The plate n on the end of the plunger F has a projection n2, Fig. 15,fitting one of the nicks in the type, and the plate 7c' of the clamp Kis notched at 70S, as shown in Fig. 14, to correspond with this nick, sothat it will pass the projection n2 when forcing the type into thechannel, and there is a nick-guide n in the channel, which holds thetype in proper position. I preferably make the plate n as shown in Fig.15, the projection n2 being carried by an adjustable section n2 of theplate IIO n. Two edges of the type are dressed by cutter-plates p p asthe type is carried forward by the plungers F F from the mold to thechannel s, and. the other two edges are dressed by cutters 19 as itpasses through the channels. At the back of the channel is the cutterwhich nicks the base of the type. These parts are the same as in themachine for which I have applied for Letters Patent ofthe United States,Serial No. 576,036, and need not be described in detail.
